In the process of changing an internal fuse I dropped the fuses, Made a error or two replacing the fuse placing the fuse incorrectly. Now I see EPC, check engine light, another warning light.

This 2013 A6 has 58,000 miles, no problem until i changed the fuse.

Any suggestions

Go to the cars manual and check all your fuses are correct. There should be a full map of the fuses and the rated amperage needed. Replace as necessary. Disconnect battery, wait 30 minutes. Make sure you have the radio code before disconnecting the battery. Reconnect and see if the errors clear. CEL may not clear for a few drives. Good luck.
